To all whom it may concern:

Be known that I, Annmrna M. Barns,

a citizen of the United States,residing at Chicago, in the. county of Cook and State of Illinois, have invented a certain new an useful Improvement in Bag-Fastening Devices, of which the following is a specification. 4

The table A-is mounted upon the sup ports A. and carries the bearings A in which'rotates the. shaft A carrying between the bearings, the. pulley A and being surrounded at one end bythe spring A which is fixed to ,one end of the shaft and at the .other vend to the table A. The mandrebB which is carried upon the shaft A and pro jects beyond the surface of the table A, carries loosely about it the bag tyingrings Ii and has embedded therein the inner ends of grip the top of the bag.

- bag '13 is shown held by the hand B of the 36 operator and in. engagement at its top with one of the rings B which is held upon the hooks B. The belt C is wound. at one end aboutthe pulley A and in engagement at its other end with the lever C which is For instance,

closely together as the ring bottom of the table A and which carries at its other end the plunger C in engagement with the solenoid C operated by the battery C whose eireuitis closed by means of the push button C, In Fig. 3 I have shown a'pla-n view of the bag tie as it appears when it 'hasbeen tightened about theneck of the bag. The circular loop D engages the top of the bag, and 1s connected by means of the twisted portion D with the elliptical loop or key I) which is formed by the hooks B and may be used to unwist the loop to release the bag.

I have shown in my drawings an operative device, still it will be evident that many changes might be made in the size, shape At any rate,

and arrangement of the parts wi'thout departing materially from the spirit of'my invention, and I wish, therefore, that-"my drawings be regarded RSIIX' a 'sensediagram- The use and opeiati n of my invention are as follows :-The top of thebag to be' tied is: slipped between the parallel spring rods so that the bag is supported thereby and a ag projects above them. Th operator then gathers the bag together in I it between'these rods, thus folding the top of the bag. One of the rings isthen drawn ofi the mandrel and slipped over the top of the bag and the ba is withdrawn from between the spring r s, the ring being drawn with it until it is engaged by the hooks at the ends of the rods. The operator'then presses a button which excites the solenoid, which solenoid o erates a lever to unwind the belt from a at the shaft on which the mandrel is mounted, thus rotating the shaft and there by twisting the wire ring: and causing it to ,LIhe. ring is then isengaged from the rods and'the spring on the shaft returns the mandrel to its original the belt on the 4 pulley. It. will be observed'that the outer hook carrying ends of the rods are divergent This arrangement provides for any local change in conditions attending the bags to be tied. it the fabric of one bag is thicker than another, it will be evident that it will re uire a longer ring to surround it and this increase in length must be'taken away from the twisted portion. This will result in drawing the spring rods more is wound up and decreasing the size of the, ellipticalloo or the elasticity of t es e rods provide at'means for holding the wire means will always remain in contact with it but are adapted to give before the ring breaks, thus preventing a rupture in the ring either in the key engaged by the hooks or in the loop engaging the In actual practice the result of this elas'tic or flexiblearrangement is that the 'tie'as shown in Fig. 3,- twists in both directions from the center and the holding loop is constricted by the reduction in the cross seetionai area of the bag engaging circle and the two rods are caused to slightly approach by the increasing tension in the key mandre I .the operator fer rotating said mandrel 1n member. The flexibility of the rods thus operates to revent parts breaking of the portion of t e wire which forms the key since the tendency of each of the loops to decrease equally as they are twisted would create too great a strain in the key loop if it were held 9n rigid holding bars.- The fiexibility of the fingers. takes up this decrease in size an prevents breakage.

I claim 5-- a A ba means responsive to the will of on direction and automatic means for sub tying .deuice comprising a rotatable i sequently returning it to its original posi vtion, and a Jectmg outwardly from the end of said manpair of parallel spring arms prodrel substantially in line with the axis thereof, said arms terminating" in outwardly ADELMER BATES.
